As noticed earlier by some Twitter users, and the Verge blog, Siri responds in a catty way against the headgear if a customer says “okay, Glass” as a command, which is how customers speak commands to the Google headset.

And in case anyone was curious, Siri does not want to change identities. “I’m not Glass. And I’m just fine with that,” she says.

An Apple spokeswoman declined to comment.

A Google spokesman offered the following statement on behalf of Google Glass: ”Siri, it’s not you, it’s me. You see, I just met Google Voice Search and fell hard for her. She doesn’t just listen; she understands me.”
